Question

The opposite of a wind turbine is an electric fan: The electric energy that powers the fan is converted to the kinetic energy of moving air. A fan is putting 1.4 J of kinetic energy into the air every second. Then the fan speed is increased by a factor of 2. Air moves through the fan faster, so the fan moves twice as much air at twice the speed.

          The opposite of a wind turbine is an electric fan: The electric
energy that powers the fan is converted to the kinetic energy of
moving air. A fan is putting 1.4 J of kinetic energy into the air
every second. Then the fan speed is increased by a factor of 2. Air
moves through the fan faster, so the fan moves twice as much air at
twice the speed.
